Upgrading a Firmware Image Using TFTP
Before downloading a new version of the AT-S79 management software
onto the switch, note the following:
ˆ Both models of the AT-GS950 Series use the same AT-S79 software
image.
ˆ The current configuration of a switch is retained when a new AT-S79
software image is installed. To return a switch to its default
configuration values, refer to “Returning the AT-S79 Management
Software to the Factory Default Values” on page 53.
ˆ Your network must have a node with TFTP server software.
ˆ You must store the new AT-S79 image file on the TFTP server.
ˆ Start the TFTP server software before you begin the download
procedure.
ˆ The switch where you are downloading the new image file must have
an IP address and subnet mask. For instructions on how to configure
the IP address on a switch, refer to “Configuring the IP Address,
Subnet Mask, and Gateway Address” on page 34 or “Enabling and
Disabling the DHCP Client” on page 37.
Caution
Downloading a new version of management software onto the
switch causes the device to reset. Some network traffic may be lost
during the reset process.
This procedure assumes that you have already obtained the software and
have stored it on the computer from which you will be performing this
procedure.
To download the AT-S79 image software onto the switch using TFTP,
perform the following procedure:
1. From the Tools folder, select the Firmware Upgrade folder.
2. From the Firmware Upgrade folder, select via TFTP.
